Apples and some other fruits undergo a process called enzymatic browning when cut and allowed access to the air. The process is a bit complicated using the enzyme polyphenoloxidase which results in the brown pigmentation.
well when it hits the air the air does somthing that it turns brown but i don't know why and how!!! SRRY!!!!!
Bananas, apples, pears, strawberries, celery, avocado, and potatoes all turn brown if left out for long enough.
To make caramel for apples, you can melt sugar and butter in a saucepan until it turns golden brown. Then, stir in cream and vanilla extract until smooth. Dip your apples in the caramel and let them cool before enjoying.
When exposed to air, apples turn brown due to oxidation. Lemon juice is rich in vitamin C, which is a natural antioxidant, and stops the oxidation process that turns apples brown when exposed to air. It also lowers the pH (making it more acidic) which is hostile to some of the common microorganisms.
To keep apples from turning brown add either powdered ascorbic acid or lemon juice and water. Cover the apples with plastic wrap placed directly on top of the apples.
Red apples have a larger anus to let out poo.
Oxidation causes apples to turn brown. The browning you see is a result of the polyphenol oxidase (PPO) enzymes oxidizing.
It makes it turn brown
because of its sugars
Fruits such as apples and pears will rot if exposed to certain fungi. These fungi are relatively weak but can attack damaged or overly ripened fruit. When fruits such as apples ripen, they give off a gas called ethylene. Ethylene gas accelerates the ripening process, which will lead to over ripening. The easiest way to prevent browning is to put the sliced apples in water. You can also squeeze like lemon juice on and helps it keep from browning. Most of the time apples brown when cut them. Apples can turn brown even when they are not cut though, but it takes considerably longer to brown. Basically because the apple contains Iron. The iron inside the apple rusts when it comes in contact with air and that's why it turns to that brownish color.
Apples will ripen faster on the counter than in the fridge.
